Ryan Murphy has cast two talented, well-known actresses to lead his sexy HBO pilot.

Fox’s Fringe star Anna Torv and veteran performer Jennifer Jason Leigh (most recently seen on Showtime’s Weeds and ABC’s Revenge) have joined the cast of Open.

The pilot is described as “a modern, provocative exploration of human sexuality and relationships.” Anna Torv will play Windsor, “a yoga instructor in a long-term relationship with Holly (Jennifer Jason Leigh), but upon meeting Grace feels an instant connection.” Now Murphy just needs to cast Joshua Jackson and John Noble to bring the dreams of Fringe fan fiction to life!

The actresses join actors Scott Speedman and Wes Bentley, who were previously announced.

Open is from American Horror Story writer-producer Murphy and Dexter co-executive producer Lauren Gussis; it’s produced by Fox 21.
